How to use the graph

Similarity map

Each dot is a game placed from its motivation profile relative to this page’s game. Direction shows which motivation differs most; distance along that axis shows how large the gap is.

  • Purple star: this page’s game at the centre — everything is relative to it.
  • Direction: each axis is a main motivational difference vs this game (e.g. more / less competitive).
  • Distance on an axis: how large that difference is (ring scales show +/− points).
  • Coloured chips: click to highlight games that mainly differ on that motivation; click again to reset.
  • Dotted line: link between this page’s game and the one selected for comparison.
  • Hover a dot to preview that game in the panel on the right; click to keep that comparison.
  • Scroll or double-click the chart to zoom.

How to read the map This is a polar difference map: direction = which motivation differs, and distance = how much (same units as the sidebar deltas).
